Since premium gas is now $3.11 a gallon in the Metro Phx,Az area I have to ask,does it help the fuel mileage? I know in theory if it has more power it should be more effiecant.That is if you keep your hand out of it somewhat.I also know a lot of people that ride don't worry about gas too much.I feeled up today and it was not on reserve and it took almost $10. It still a lot,lot better than the old truck even goin above the speed limit.
